Troubleshooting
Problem: The scanner won’t scan.
Check for one of these possible problems:
• Is a cable loose or not plugged in securely? Inspect all cable connections. Make sure all the
cables are plugged in securely.
• Is the scanner’s status light on? Turn on the scanner’s power. If the status light doesn’t come on,
plug the power supply into another electrical outlet.
• Did you restart the computer after installing the software? If you didn’t restart the computer, it
may not have loaded all of the software files. Try restarting your computer.
• Did you plug the scanner into a USB hub? Try plugging the scanner directly into a USB port on
the computer.
• Did you select another TWAIN source for acquiring images? If you use multiple TWAIN devices
with your computer, you may have selected another source for images. Make sure TWAIN: Xerox

Problem: The scanner does not work after performing a Windows System Restore.
The system restore process may have corrupted some of the driver components. It is recommended
that you reinstall your scanner driver.
Problem: The scanner buttons do not work after scanning with Windows Image Acquisition (WIA).
After performing a scan using the WIA interface you must close the application you were using before
scanning with the buttons on the scanner. This does not occur when scanning using the TWAIN or ISIS
interface.
Problem: The scanner doesn’t work after the computer has been sitting idle for several hours.
To resolve the problem, simply turn off the scanner power then turn it back on again.
This may occur after Windows goes into power saving mode to “hibernate” the computer into a low
power state. When you move your mouse or type on the keyboard it “wakes” the computer back up and
restores full power to the system. This power fluctuation during the computer’s hibernating period may
sometimes cause the scanner to lose communication to the computer.
Problem: PaperPort reports an error that it cannot allocate enough memory to perform internal
critical operations.
Close any other active applications so that additional memory is available. If you click Continue,
PaperPort moves the file to the PaperPort data directory and renames the file with the prefix “bad.”
This allows you to recover the file later. To recover the file, import it into PaperPort by using the Import
command in the File menu.
